Re: Segmented Control widget mouseDown

[Richmond Mathewson via use-livecode]

I was fiddling around with this at the weekend trying to work out how it 
worked,

and was surprised by the lack of mouseDown/Up as well.

Is there any way to capture mouseDown/Up on a Segmented Control 
widget? hiliteChanged is the only message that is documented or shows 
up in the Script Editor and standard mouseDown/Up handlers aren't 
acknowledged. Am I missing something or does this need to be enabled 
first in LCB and then passed to LC?


I tried putting a mouseDown/Up on the widget and it doesn't trigger. I 
tried putting the widget in a group by itself (a trick I learned so I 
could put Effects on widgets) and applying the mouseDown/Up script to 
the group and it doesn't trigger. I add another object to that group 
and when I click on that other object the group script finally 
triggers, but not when clicking on the widget.


My problem is that I can't find a way to determine if the item of the 
Segmented Control that was clicked was already the current 
hilitedItem. I know I can toggle the hilite, but I just want to know 
if the current "active" item has been clicked again.


My goal is to replace 3 buttons that I use to sort a dataGrid by 3 
different filters. Currently I have the buttons scripted to act like a 
group of radio buttons (but they are standard buttons for easier 
skinning) and realize if they are the "active" button and toggle 
sorting by descending/ascending for that filter (the iconPresetName of 
a SVG widget is also toggled at this time to indicate the sort 
direction).

I had the same experience as Andrew. I would love to see a mousedown and 
mouseup message sent to this widget.
